Definitions

  • the invention relates to an all-current sensitive residual current protective device with a first, independent of the mains voltage Sensor device and a second, mains voltage dependent Sensor device.
  • Residual current circuit breaker independent of the mains voltage and a line voltage-dependent residual current circuit breaker (DI-protective switch).
  • the two circuit breakers each have a total current transformer, by led by the conductors of the line network to be monitored are.
  • Both summation current transformers each have a core a winding to which a sensor device is connected which in turn is connected to a triggering device is.
  • An impermissible fault current occurs in the line network on, it is replaced by the summation current transformer of the associated one Sensor device detected. Via the release device the conductors of the network are separated.
  • Such a residual current device is for example from the DE 197 35 412 A1 known.
  • the well-known AC / DC sensitive residual current device is used in electrical systems to protect people and systems used.
  • the pulse current sensitive detection is in the fault current protection device known from DE 197 35 412 A1 implemented independently of the mains voltage, whereas DC-sensitive detection depending on the mains voltage is realized.
  • a reaction of the first sensor device to the triggering behavior of the second sensor device is to be avoided in the control line leading to the triggering device first decoupling device switched.
  • the known residual current protective device has their construction (2 summation current transformers, up to 2 decoupling devices) a relatively large volume and thus a corresponding energy consumption and a corresponding Heat radiation on.
  • the object of the present invention is therefore to provide a residual current protective device of the type mentioned at the beginning create that is simpler and a smaller size having.
